main/openrc: upgrade to 0.35.5

[jirutka]

There’s one important change:

https://github.com/OpenRC/openrc/blob/master/NEWS.md:

In this version, the cgroups mounting logic has been moved from the sysfs service to the cgroups service. This was done so cgroups can be mounted inside an lxc/lxd container without using the other parts of the sysfs service.

?As a result of this change, if you are upgrading, you need to add cgroups to your sysinit runlevel by running the following command as root:

# rc-update add cgroups sysinit

I’m not sure what does it affect. Where is default set of services populated?

I think this is something that is sort of expected to be mounted, like /sys itself. It seems like openrc itself can set limits on services it manages, so openrc itself may need it.

Default services are set up on first boot in initramfs-init: https://git.alpinelinux.org/cgit/mkinitfs/tree/initramfs-init.in#n506 and then copied over with setup-disk.

One way to do it would be to have a pre-install/update script that checks if sysfs service is started and if it is, create a symlink in /etc/runlevels/sysinit.

I don't think many things will break if its not missing, but it is difficult to know for sure.

looks like community/cgmanager/cgmanager.initd also needs cgroups.

Are we going to do this for 3.8?
Looks like we are many releases behind.

ps, why is only the subject of this PR 0.36?

Don't forget about $j

Cgroups support is optionally, OpenRC can work even without it.

Are we going to do this for 3.8?

I’d like to, ’cause we’re many releases behind.

ps, why is only the subject of this PR 0.36?

@jirutka your patches are for openrc 0.35.5 while the subject says 0.36 which is the latest version.

your patches are for openrc 0.35.5 while the subject says 0.36 which is the latest version.

Huh, I have no idea why I did that. It’s most likely a mistake.

[jirutka]

Aha, 0.36 has not been released yet. But still I don’t know why I wrote 0.36 into the PR’s title.

[clandmeter]

hmm, i think because its listed in https://github.com/OpenRC/openrc/blob/master/NEWS.md
